Verizon Phone Warning
Many apps are extremely useful. We used them all the time. Using our American AT&T iPhone in Singapore was fine, after we unlocked it. Older Verizon iPhones from the USA do not work internationally, since they use CDMA technology. Verizon does sell several “World Phones” which work with SIM Cards. Check your phone before leaving.
We have done the research on our last trip and are sharing the findings with you.
We also have articles on using prepaid SIM cards in other countries:

Here are some tips on using your iPhone in Singapore
You can only use foreign SIM cards in an unlocked iPhone or Android Smartphone. A locked smartphone only works on the original cell phone carrier. Most cell phone carriers in the US, including AT&T, allow you to unlock Smartphones after your 2 year contract has been fulfilled. T-Mobile requires 18 months of payments before they will unlock a cell phone under contract. You can alternately purchase an unlocked Smartphone from Amazon, eBay, etc.
If you prefer to unlock your iPhone, you can try jailbreaking it. Jailbreaking and unlocking iPhones are not easy tasks. One slip and you may have bricked your expensive smartphone. You can buy a pre-jailbroken/unlocked used iPhone from eBay or Craigslist. Unlocked iPhone 7’s typically cost around $150.
This article also applies to using prepaid SIM Cards in the iPhone 11, XS, X, 8, 8+, 7, 7+, 6. 6+, 5s, 5c, 5, and iPad with 4G or LTE. Android Smartphones utilizing GSM technology are also supported.
Different Smartphones use different sized SIM cards. Most foreign cell phone carriers sell smaller micro-SIM (iPhone 4, 4S, older iPad) and nano-SIM (iPhone 11, XS, X, 8, 8 Plus, 7 Plus, 7, 6 Plus, 6, 5, 5s, 5c, iPad Pro, mini and Air) for use in a variety of Smartphones. Newer places have 3 in 1 combo packs to accommodate all sizes. You should remove the SIM card from your phone before you attempt to purchase a prepaid SIM card in another country.
Main mobile carriers in Singapore
The main cellphone carriers in Singapore are
- M1 Limited
These carriers support GSM900/1800/2100 frequencies.
Singapore SIM Card
We bought our card at the Airport. Turn keft after exiting customs, look for the first stall next to Tourism Information.
We need at least 5GB to be shared by 4 users over 3 days. We choose Singtel hi!Tourist SIM SG$30 This includes:
- Valid for 12 days
- 100GB 4G local data
- Unlimited local calls & sms
- 90 minutes international calls
- 3GB data roam for Australia, Malaysia, Indonesia and Thailand
Share the Connection with Mobile Wi-Fi
This Singapore SIM Card also worked in our Mobile Wi-Fi (Mi-Fi), a HUAWEI E5577. We connected 4 phones to this via Wi-Fi! No need to get 4 separate SIM Cards.
You can rent mobile Wi-Fi devices at the airport, but beware that they sell out during holidays like Chinese New Year.
These instructions should work for other smartphones including Android smartphones that support American GSM networks from AT&T and T-Mobile.
